Review on 🚗 Kwiksen 234-5430 Upstream Air Fuel Ratio Sensor AFR Oxygen Sensor Compatible with Elantra 2.0L 2003-2009, Spectra 2.0L 2004-2009, and Spectra5 2.0L 2005-2009 by Sherman Lancaster

This fixed my 2004 Elantra. P0030, P2626, P2271 were prefix codes. I drove 200 miles with the new sensor so it looks good. I'll look at the car over the weekend. Why my minus one star? (4 instead of 5 stars). My first package I received, the box was the correct part, but the actual part inside was the BOTTOM FLOW sensor, not the HIGH FLOW sensor that I needed or was in the picture. I think it was just an accident. The reorder came 3 days later and the box had the same (correct) part number, but this time it actually had the correct (upstream) sensor. Again, my first (erroneous) order was probably just an accident. Luckily the extra 3 days didn't hurt me too much. Tip: If you are replacing your part, see the part before ordering. Unplug and check if you have a 4 or 6 pin plug before ordering.
